Domain Socket Support

MongoDB has built-in support for connecting via Unix Domain Sockets and will open the socket on startup. By default, the socket is located in /tmp/mongodb-<port>.sock.

To connect to the socket file, specify the path in your MongoDB connection string:

<?php
$m 
= new MongoClient("mongodb:///tmp/mongo-27017.sock");
?>

If you would like to authenticate against a database (as described above) with a socket file, you must specify a port of 0 so that the connection string parser can detect the end of the socket path. Alternatively, you can use the constructor options.

<?php
$m 
= new MongoClient("mongodb://username:password@/tmp/mongo-27017.sock:0/foo");
?>
